This report presents a historical account of the development of rear lighting systems. The account is based partly on a comprehensive review of the available documented sources. Various details of both technical developments and lighting standards are covered. Then the rear end crash situation is discussed. It is noted that rear end crashes constitute a large and increasing problem in present road traffic. This is followed by an analysis of the various functions of rear signalling systems and the extent to which the present rear lamps accomplish those functions.
